Study on pharmacokinetics of loxoprofen tablets in healthy volunteers |

Abstract: | AIM: To study pharmacokinetics of loxoprofen tablets in healthy volunteers by a new RP HPLC method. METHODS: The separation was performed on Hypersil ODS(200 mm×4.0 mmID,5 μm)column and the mobile phase system consisting of acetonitrile, tetrahydrofuran and 0.02 mol·L -1 phosphate buffer (pH2.5) with the ratio of 30∶4∶66 and that was suitable for the biosample assay of loxoprofen tablets. The detection wavelength was 222 nm. Ten healthy volunteers were given orally with a single dose of 60 mg loxoprofen tablets and the plasma concentrations of loxoprofen were handled with 3P87 program and the theory of statistical moment. RESULTS: Loxoprofen peaks in plasma samples were not interfered under the optimal chromatographic conditions and the good linearity was obtained between the peak areas of loxoprofen and the concentrations of loxoprofen in plasma samples. The main pharmacokinetic parameters were as follows: T max was (0.6±0.3) h, C max was (3.9±1.1) mg·L -1 , T 1/2 was (2.0± 0.4 ) h, MRT was (2.0± 0.3 ) h, AUC 0~∞ was (7.1±1.3) mg·h·L -1 ,respectively. CONCLUSION: This RP HPLC method is simple, quick, accurate, reliable,and suitable for the pharmacokinetic study of loxoprofen tablets. |
